[QUOTE="dtravis7, post: 1810354, member: 8287"] Jake, I am 99% sure with one of the Sierra and High Sierra updates updated the Firmware on both my 2010 iMac i& and MBP late 2011. Charlie I believe is right and it's a firmware issue. I will try my factory from Apple Snow Leopard DVD later in my MBP and report back. [/QUOTE]
